Model: Archer C5400X  
Hardware Version:
Firmware Version: 1.1.2

My modem seems to be dropping my fiber connection multiple times a day. I have tried my provider and my connection is not going out with them. The only way we fix it is to hit reset on the modem.  I have tried switching the cables between the modem and router, updated the firmware, changed the power supply locations. Is there anything else I can try? I don't know what else to try.

@Mattlaplant 

 

If the LED lights on the modem change when the issue happens it may be the modem that is possibly the issue?

 

Have you tried bypassing the TP-Link router and leaving a computer connected for as long as the TP-Link was connected for the issue to happen again?

@Tony  The modem flashes failure when it goes out. I will try connecting my laptop directly the next time it drops and see what the connection is on that.
